  • Publication number: 20240162263
    Abstract: To provide an imaging device that can suppress color mixing between pixels. An imaging device includes a first semiconductor substrate having a plurality of photoelectric conversion elements, a lens body provided on one surface side of the first semiconductor substrate, and a wiring layer provided on an opposite side of the one surface of the first semiconductor substrate. The first semiconductor substrate includes an inter-element isolation part disposed between one photoelectric conversion element and another photoelectric conversion element adjacent to each other among the plurality of photoelectric conversion elements. The wiring layer includes a first isolation part disposed at a position facing the inter-element isolation part. The first isolation part includes a first low refractive index region and a first high refractive index region in contact with the first low refractive index region. The first high refractive index region sandwiches the first low refractive index region from both sides.
